| // RECONSTRUCTED SOURCE: obfuscator_test.cpp | |
| // Reverse-engineered from IDA decompilation dump (67 functions, entry 0x115F0) | |
| // Target: x86_64 Linux, C++20 (std::format), libstdc++, pthreads | |
| // Compiler: GCC (inferred from libstdc++ ABI, __cxx11::basic_string layout, | |
| // magic-number divisibility optimizations, fsqrt intrinsic usage) | |
| // ============================================================================= | |
| // | |
| // ASSUMPTION REGISTER: | |
| // [A1] String literals (rodata pointers 25309, 25517, 25957, 27406, etc.) | |
| // reconstructed from context (syscall semantics, size constraints, SSE | |
| // verification patterns). Stress test: any 31-byte/42-byte string with | |
| // matching content would produce identical control flow. | |
| // [A2] Thread names from unk_6DA0 array inferred as generic indexed names. | |
| // Actual rodata content unknown without binary .rodata dump. | |
| // [A3] Global addresses (unk_21700, unk_21730, mutex, stru_21708) mapped to | |
| // named globals. Actual symbol names unknown (stripped binary). | |
| // [A4] Timespec constants (unk_5970, unk_5A00) for nanosleep inferred as | |
| // small durations (~100ms). Exact ns value unknown. | |
| // [A5] SSE comparison constants (unk_5A20, unk_5AB0) in pipe test inferred | |
| // from "known test string" pattern. Exact bytes unknown. | |
| // [A6] logic_tree() and bitwise_forest() were fully constant-folded by the | |
| // compiler. Reconstructed implementations produce the observed outputs | |
| // (657 and 0x22694D19 respectively) but internal structure is one of | |
| // many possible originals. | |
| // [A7] std::format usage inferred from format parsing infrastructure | |
| // (sub_12530/sub_1C130/sub_12F80 etc.) and format_error exception types. | |
| // The exact format string is reconstructed from the output pattern. | |
